The Register had an interesting article on the analysis of what may get classified as the worlds oldest computer (2000 years old – Greek.) Apparently it’s been known for a while (discovered in an old shipwreck around 1900). It’s been called the “Antikythera Mechanism” and has more than 30 dials and wheels. Anyway, it’s currently been undergoing detailed imaging analysis which has uncovered some new clues which may reinforce a theory that it was designed to track/predict planetary locations (Mercury, Venus, Mars, Jupiter and Saturn were known to the ancient Greeks.)
